When beginning a new chapter, read through it quickly the first time, just to give yourself a good feel for what it is about. If you are really on the job you will have done this before the class lecture on the chapter. You will understand what's going on in class much better if you do this.

Study groups can be very helpful. Keep the group small though, no more than three or four people.

Finally, keep a positive outlook! Geology can be hard, but with a good attitude and approach, you will succeed in mastering it!
